What are breadcrumbs in crash instrumentation?

Breadcrumbs are a chronological log of events, such as screen transitions and API calls, that provide a trail leading up to the moment of a crash.

Can it help diagnose ANRs or memory issues?

Absolutely. It includes strategies for instrumenting platform-specific issues like Android ANRs (App Not Responding) and iOS Watchdog kills.

How does this improve standard crash reporting?

It adds actionable context—such as breadcrumbs, user segments, and specific job steps—that standard SDKs often miss, making it easier to reproduce and fix issues.

What mobile platforms does this skill support?

The skill provides implementation patterns and guidance for iOS, Android, and React Native development environments.

Does this skill help with data privacy?

Yes, it includes specific guidelines on what not to attach to logs, such as PII or full request bodies, to ensure compliance with privacy standards.

Mobile Development

Implements comprehensive crash reporting and diagnostic context for mobile applications to accelerate debugging and root cause analysis.

About

The Mobile Crash Instrumentation skill provides developers with standardized patterns for capturing high-context crash reports across iOS, Android, and React Native platforms. It focuses on making crashes actionable by implementing breadcrumb strategies, defining error boundaries, and attaching critical metadata like navigation state and user segments. By following these best practices, developers can transform cryptic stack traces into clear narratives of user sessions while maintaining data privacy and avoiding common pitfalls like PII exposure.

Key Features

Privacy-first logging guidelines to prevent PII exposure
Context-aware crash capture for iOS, Android, and React Native
Cross-platform error boundary implementation patterns
Platform-specific handling for ANRs, OOMs, and Watchdog kills
Standardized breadcrumb logging for navigation, network, and state changes
98 GitHub stars

Use Cases

Configuring a mobile crash reporting SDK with actionable breadcrumb trails
Setting up robust error handling to prevent silent failures in React Native apps
Diagnosing complex UI-related crashes by tracking screen transition history
